Findings reveal that Green Culture exerts a strong direct and indirect impact on sustainability through PEB. GTL demonstrates the importance of leadership commitment, while GHRP enhances outcomes when integrated with cultural and leadership strategies. The R2 values indicate strong relationships between Green Transformation Leadership, Green HR Practices and Green Culture with Employees’ Pro-environmental Behavior and between these factors with Environmental Sustainability. These components together produce essential outcomes for promoting sustainable practices in organizations. The proposed model underscores the role of employee engagement in driving sustainability and offers practical recommendations for business leaders and policymakers.

The results of the present study will enable tracing the root cause for the solid wastes in the rice fields. A systematic sampling of the paddy rice cultivation fields revealed the presence of eight types of solid wastes with the dominance of the various forms of plastic material. These solid wastes could be linked with nine different sources of origin, with the dominance of the packaged food industry. A significant (P &lt; 0.05) difference in the solid waste types and the sources could be portrayed through the bipartite network analysis. This approach provides a robust framework for tracing the origin of waste and targeting key sources for intervention. Information obtained through the present study will prove helpful in understanding the infiltration and establishment of the plastics and allied polymers in rice fields interfere with the structure and functions of the community assemblages. The plastic waste types and its multiple links provided evidence for the origin and possible entry into the rice field system.

These findings highlight the potential of increased temperature water-based extraction methods but also underscore the need for further optimization.

This study examined the high content of bivalent ions (Ca²⁺ and Mg²⁺) in RO reject brine for producing reactive quicklime and magnesia via selective precipitation. Various precipitating agents were evaluated at various molar ratios to discuss the high purity and process efficiency. The oxalic acid dosage was evaluated at a molar ratio (C₂H₂O₄/Ca²⁺) of 2 which led to high recovery efficiency of calcium oxalate monohydrate (97.5 ± 0.5 %). The theoretical study using PhreeqCI3 via the Pitzer model was used to model the precipitation behavior at selected conditions. The alkaline caustic ash dosage was set at the molar ratio (NaOH/Mg²⁺) of 3, corresponding to the highest extent of precipitation of brucite (97 ± 0.5 %). Further, the calcination of the precipitated solids for 2 h at 900 °C and 500 °C produced the reactive quicklime and magnesia. The characterization of produced oxides at the optimized parameters was designated and discussed based on the composition, microstructure, and reactivity. The surface areas of the obtained oxides were 10.4 m²/g and 58.3 m²/g, respectively, according to the BET analysis. The energy consumption and production cost for generating high-purity oxides from desalination waste revealed that RO reject brine is an additional source for recovering alkaline earth oxides with high reactivities and allowed to minimize the environmental impacts resulting from desalination plants.</div></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"3 3","pages":"Article 100218"},"PeriodicalIF":0.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many LAs around the world prefer composting organic waste as a means of waste volume (and transport cost) reduction and cost recovery option within a circular economy framework. To optimize compost production with a focus on cost recovery, a systematic study was conducted at 22 composting stations located in Sri Lanka’s highly populated Western Province. The study examined process management from organic waste collection to product quality and cost recovery via compost sales. Collected organic waste conversion into compost was varied between 1 % and 15 % and time taken for completion of the process varied between 2.5 – 4.5 months. No standard operating procedure was observed though input organic matter was of similar nature. Excess leachate and odour production reported by 59 % of the surveyed stations. Complete analysis of compost quality was hardly reported by any LAs and no sales and marketing strategies were adopted to boost the cost recovery. Poor data management has hindered the identification of improvement opportunities and performance benchmarking of composting stations run by LAs. To address these significant performance variations observed among the stations, a monitoring and evaluation framework is proposed based on four composite key performance indicators (KPIs): General Facility Management Index (GFMI), Composting Process Management Index (CPMI), Compost Quality Index (CQI), and Cost Recovery Index (CRI). These KPIs serve to benchmark performance and identify incremental improvement opportunities at each station. However, to address institutional and human capacity challenges an institutional partnership model is also proposed, which could incentivize the implementation and achievements of the KPIs while reducing the pressure on LAs to reach the compost market.</div></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"3 3","pages":"Article 100217"},"PeriodicalIF":0.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144178032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing VOSviewer and RStudio, the analysis maps the intellectual structure, thematic evolution, and global research dynamics of AFNs over the past three decades. The results reveal an average annual growth rate of 11.19%, with a sharp increase in publications after 2020, driven by heightened interest in resilient, local, and circular food systems. Co-word and cluster network analyses identify four major thematic domains: (1) local food and consumption patterns, (2) sustainability and environmental impacts, (3) governance, policy, and social justice, and (4) community participation and social innovation. Key theoretical frameworks underpinning the field include Actor-Network Theory, Convention Theory, and the Theory of Planned Behavior. This study distinguishes itself by framing AFNs as upstream system-level interventions with the potential to complement or substitute downstream technological approaches to waste management. It highlights AFNs’ unique contributions to reducing food loss and waste, strengthening local economies, and fostering inclusive development. The findings also reveal a research gap in the Global South, where AFNs could address food safety and local poverty.

This review addresses the growing research need to valorize banana agro-waste, particularly green bananas and peels, for the development of biodegradable biofilms as sustainable alternatives to plastic packaging. The novelty of this work lies in its focused examination of banana-derived biopolymers, such as starch and fibre, and their capacity to form eco-friendly, mechanically robust, and biodegradable films suitable for food preservation. In addition to packaging applications, the review explores the broader multifunctionality of banana plant components across textiles, medicine, and bio-based industries. By synthesizing current literature, this article presents a comprehensive overview of banana waste utilization for both economic and environmental sustainability. It also identifies existing research gaps and outlines future directions to optimize biofilm formulations and encourage holistic, waste-minimizing approaches in banana production.
